નોડ-રેડ કન્ટેનર બનાવવું
આ માર્ગદર્શિકા Pixsys પર Node-RED કન્ટેનરના ઇન્સ્ટોલેશનને આવરી લે છે. WebPanel “WP” and TouchController “TC” series.
Displaying the Node-RED dashboard on the screen is possible only on WP – WebPanel devices and on TC – TouchController panels with the “WebVisu” license only. On TouchController – TC panels with a “TargetVisu” or “TargetVisu + WebVisu” license, it is not possible to display the Node-RED dashboard.

Access the device in configuration mode by holding down the STOP button that appears at startup.
નીચેના ઓળખપત્રો દાખલ કરીને રૂપરેખાંકન કન્સોલને ઍક્સેસ કરો:
વપરાશકર્તા નામ: વપરાશકર્તા
પાસવર્ડ: 123456
If the device IP is known, it is also possible, and recommended, to access the configuration console from a browser on the user’s PC by accessing the address: https://device-IP-.9443/ અને ઉપરોક્ત ઓળખપત્રોનો ઉપયોગ કરીને.
નોડ-રેડ માટે ફોલ્ડર બનાવી રહ્યા છીએ
જે કન્ટેનર સક્રિય થવાનું છે તેને યુઝર ડેટા સ્ટોર કરવા માટે જગ્યાની જરૂર છે.
For this purpose, in the devices, there is a folder /data/user.
Using WinScp or another sFTP access software, create a folder node-red within the path /data/user, following the steps below:
- Open WinSCP, connect to the device using the IP and credentials already used to access the configuration console, and choose /data/user
- From the Menu “New” select the option “Directory…”.
- Create the folder node-red, enabling all “R/W/X” permits:
The same process is also possible by SSH access and using the following prompts:
mkdir -p /data/user/node-red
chmod a+rwx /data/user/node-red
Download of the container
મેનુ બાર પર "પોડમેન કન્ટેનર" ઍક્સેસ કરો:
Select the option“Download new image” in the menu to the right with the three-dot icon
Select the search area “docker.io“
Type “node-red” in “માટે શોધો"
Select official image “docker.io/nodered/node-red”:
Then press “Download” and the download of the image will start.
This is a several hundred Mb file; depending on the internet connection, it may take several minutes.
જ્યારે ડાઉનલોડ પૂર્ણ થશે, ત્યારે તે શક્ય બનશે view ઉપકરણ પરની છબી:
કન્ટેનર બનાવટ
In the “Containers” Tab, press the “Create container” button. A menu will open to configure the container you want to create.
Fill in the “Name” field with a name of your choice, replacing the automatically generated random one.
Tab Details:
From the “Image” box, choose the downloaded image as described in the previous chapter:
Configure “Memory limit” to 128 or 256 MB.
“Restart Policy” set to “Always” sets the container to start automatically and be restarted even in the event of a user-commanded shutdown.
Tab Integration:
Configure port mapping to expose port 1880 in both TCP and UDP, and map the Container Path /data, visible from node-red, in Host Path /data/user/node-red
Tab Health check:
This Tab defines the control checks on the correct operation of the container and how it will behave in case of an error.
The image below shows the default parameters:
આ સમયે એસtage, press “Create and run” and wait for the creation of the container.
કન્ટેનરનું પરીક્ષણ
When the container creation procedure is finished, the “Containers” list will display the new running container (State: Running):
Open a browser on PC and go to the page: http://device-IP.1880
ડેશબોર્ડ બનાવી રહ્યા છીએ
ડેશબોર્ડ નોડ-રેડને ગતિશીલ પ્રસ્તુત/પ્રકાશિત કરવાની મંજૂરી આપે છે web પૃષ્ઠ
Install “node-red-dashboard”, opening the Menu Manage palette:
માટે શોધો node-red-dashboard within the tab Install
Wait for the installation to be completed, and then log in to the console and import the Flow entered at the end of the guide from the menu Import:
**આ ભૂતપૂર્વ છેample code with no real purpose.
NB for the use of Node-RED and the Dashboard, please refer to the documentation available online.
એકવાર કોડ આયાત થઈ જાય, પછી આ નીચેના જેવો પ્રોજેક્ટ પ્રદાન કરશે:
દબાવો 
પ્રોજેક્ટ કમ્પાઇલ કરવા અને શરૂ કરવા માટે.
Opening page http://device-IP.1880/ui, the result will look like the following:
ડેશબોર્ડ પ્રદર્શિત કરવા માટે પેનલને ગોઠવી રહ્યું છે
At this point, for panels that allow it, access the menu WP Settings, then Main application settings, and enter URL http://localhost.1880/ui
Use the term localhost or IP 127.0.0.1 to make the browser access the device itself, regardless of its actual IP.
Upon reboot, the device will show the full-screen Node-RED Dashboard.
